SPECIFICATION forming part of Letters Patent No. 451,876, dated May 5, 1891.

Application filed May 3, 1890. Serial No. 350,530. (No model.)

T0 on whom it may concern:

Be it known that we, FRANK MEsKER and THOMAS O.ARBEGUST, of St. Louis, Missouri, have jointly made a new and useful Improvement in lVindoiwFrames, of which the following is a full, clear, and exact description.

Theimprovement relates to window-frames whose stiles are more or less composed of sheet metal, and it has special reference to mullioned windows; and it consists in the construction of the mullion, substantially as is hereinafter set forth and claimed, aided by by the annexed drawings, making part of this specification, in which Figure 1 is afront elevation of a windowframe construction to which the present improvement is adapted. The frame is broken away at the right of the mullion; Fig. 2, a vertical section on the line 2 2 of Fig. 1; Fig. 3, a horizontal section on the line 3 8 of Fig. 1, and Fig. 4 a section upon an enlarged scale upon the line 3 3 of Fig. 1.

The same letters of reference denote the same parts.

Saving as the window-frame is modified or supplemented by the improvement under consideration it may be of any of the ordinary forms of construction which may be adapted for the embodiment therein of the improvement. The frame A shown is a suitable one.

B B represent the lights divided by the mullion 0, whose construction is the feature of the improvement. It is composed substantially of the two stiles c and c, the inside finish-board c and the stud or filling-piece 0 The stiles are of sheet metal, shaped, as shown, to provide bearings c for the sashes D D and outside sash stops 0 c and to provide spaces or boxes 0 c to receive the Weights E E, and the sheet is preferably in a single piece, extending from one edge 0 of the board 0 outward and around and inward to the other edge e of the board 0 and its face 0 is preferably paneled at 0 partly to strengthen the mullion and partly to ornament it. The filling-piece extends from the board a to the face 0", and it may be a single piece, as shown in Fig. 4, or in two or more pieces, as in Fig. 3. The piece 0 serves to strengthen the mullion, also to separate the boxes a o. It is a desirable element in the construction, but not wholly essential.

F F represent the inside sash-stops, and G G the parting-strips.

The board 0 maybe of metal. The frame A at its sides may have sheet-metal stiles, such as the stile H, and they may respectively adjoin sheet-metal columns, such as the column I. The window-stool is shown at J. The window-frame at its top and bottom is constructed in the usual manner.

lVe claim- 1. A mullioned window-frame Whose mullion is composed of the sheet-metal stiles, inside finish-board, and filling-piece, said stile being shaped to provide spaces to receive the sash-weights, substantially as described.

2. The combination, in a Window-frame mullion, of the double sheet-metal'stile and the inside finish-board, said stile being shaped to provide spaces to receive the sash-weights, substantially as described.

3. The herein-described window-frame mullion, consisting of the double sheet-metal stile, the inside finish-board, and the filling-piece, said mnllion-face being paneled and said filling-piece extending from said board to said face, as described.

Witness our hands this 30th day of April, 1890.
